We do have the capacity to ship massive tonnages of grains, meat, fruits, livestock around the globe and we use it ensure sufficient pipelines to feed a billion+ global population across all seasons and weathers.

Costs at that scale are large, transcontinental railways across mountains, lifting tonnages against graivity in addition to rolling friction, braking energy and return to steady motion energy repeated for frequent stops and loading, transfer, loading times add up.

Per tonne per kilometres costs of floating container ships and binned grain ships are easily competitive.

There are points to be made about the lower tonnages of picky people foods, lobsters, fancy beef, a Bugatti Chiron tucked away amidst a cavern of self loading basic electric cars .. but there's still an underlying current need to transport food from source to demand.

The costs of global shipping transport is iron mining, steel formation, build times, fuel production, fuel side effects, and so on - fuel side effects are a bit of a pressing issue, and have been since at least that 1967 absolute banger by Syukuro Manabe and Richard T. Wetherald they chose to call Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity
